Inthe particular case of a centrifugal machin s: Sh w l t: a r pres t h Outer or main receptacle in which is contained the structure or means to be driven includ ing a basket (not shown) to receive the mateflial to betreated and the shaft Z; journaled in an arch c upstandingfrom the receptacle a. The arch supports, suitably fixed thereto, the high speed el ctric motor cl having 6 as. its armature shaft. This motor, with its source of electrical energy and the necessary .CQnductor therebetween (bath un e s ry t W) farm n. h

P sent case the means to drive said struc-- 5 ture at high speed, and for that purpose there is a manually operated starting device herein in the form of an electrical switch e, which it will be understood arranged in the conductor, 6 being the starting button of the switch and 6. its cuteout button,

The means to drive the said structure at; slow speed is. as follows; f is an electric motor mounted on the arch and having a source of electric energy the necessary conductor connecting it therewith (both not shown) and a starting device; f similar to device 6, its armature shaft 7?? being coupled to an extension shaft 9 which journaled in the arch and has thereon a worm g in mesh with a wornrwheel it freely rotative on. the. shaftv Z) and contained in and supported by a cup-like portion 0 of the arch; this worinvvl eel forms the aforesaid lower or e clutch membe Q d ve b in p evided 011 its top surface withteeth having each an inclined or cam-face 7 and a ver: tical or driving face if, Fig. 6.

Mechanism shielding the starting device 6 (so that it cannot be manipulated to start the h -sp d m er) an oupling o s tt r the l w-sp ed dr in mea s an said structure (whereby to drive the latter from the former), said mechanism being shiftable to simultaneously uncouple said low-speed driving means and structure and unshield the starting device, is; provided as follows: Splined on" shaft Z2- is the upper clutch member 2' having teeth on its lower surface to engage the teeth of the lower clutch member, each such tooth having an inclined or cam face i and a vertical or driving face 71 This member is peripher: ally grooved (Fig, 5.) to receive a collar (Fig. 3) whereby to shift the clutch mem her vertically by means of a lever 70 straddling the collar and pivotally connected therewith. A rock-shaft Z journaled in bearings m at the front of the arch 0 has at one end a handle at and is equipped with a projecting shield 0 in the form of a blade arranged to swing down into. shielding relation to the starting button 6' or up to unshield the same. This shaft; is preferabl connected with the lever by a toggle connection which will ins-u-re'against accidental fall of the lever, and consequently of clutch member 2', when elevated; this is afforded by a crank 19 on the rock-shaft and a link 9 connecting the crank With the lever and having a depending stop 7 to bear against the member formed by the rock-shaft and the other mentioned parts thereon and limit their motion in one direction past their dead-center relation relatively close to their dead-center position when, the shaft having been rocked to raise the lever, the pivot between the crank and link passes the dead center. There may also be a spring catch 8 to engage handle a and thus hold the lever elevated.

When the mentioned mechanism is in the position where the shield is in shielding position or down (dotted lines, Fig. 4-) the upper clutch member or coupler is depressed. The high-speed. motor, which has been previously stopped after a preceding operation of the machine, cannot now be started because the starting button 6 is shielded, but the low-speed motor can be started by operating its starting device f and when this is' done the basket of the machine is rotated through the coupler 2' which is now in engagement with clutch member 71, its teeth faces 7? engaging the teeth faces k of the latter clutch member. When the machine is to be operated at high speed the rockshaft Z is by means of its handle shifted to the full-line position of Fig. l, so as to unshield the starting button; but this uncouples the basket-including structure from the low-speed driving means, permitting the starting of the high-speed driving means now' to be effected without interference. Later the attendant stops the highspeed motor by pressing the button 6, and at that time resets the mentioned mechanism including the rock-shaft so as again to shield button 6 and recouple the basket-including structure with the low-speed driving means.

If the parts including clutch member 2' should be inadvertently shifted to depress said clutch member while it is rotating relatively to or faster than clutch member it no smash can occur because then the cam faces z" will wipe idly over cam faces h, the clutch members being in effect rachet members. The construction is in fact such that in the stated event member it would elevate member 2' to such an extent that it would become dogged and held again in elevated position by the toggle connection.

t is simply a disk which rests on the clutch member 2' and forms a' cover for the housing 0, thus to prevent oil or grease from being thrown out of said receptacle.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent is:

1. The combination of a rotary means to be driven, means to drive said driven means at one speed having a manually operated starting device, means from which to drive said driven means at another speed, and mechanism positioned to render the starting device manually inoperative and coupling together the second driving means and the driven means, whereby to drive the latter from the former, said mechanism being shiftable to simultaneously uncouple said second driving means and driven means and leave the starting device operative.

2. The combination of a rotary means to be driven, means to drive said driven means at one speed having a manually operated starting device, means from which to drive said driven means at another speed, and mechanism shielding the starting device and coupling together the second driving means and the driven means, whereby to drive the latter from the former, said mechanism being shifable to simultaneously uncouple said second drivin means and driven means and unshield the starting device.

The combination of rotary means to be driven, means to drive the driven means at one speed having a manually operated starting device, rotary means from which to drive the driven means at another speed having a rotary driver member revoluble concentrically on a part of said driven' means, a coupler member on said part, said members being positioned in coupled engagement with each other and one being movable to clear the other, means positioned to render the starting device inoperative and movable to render the same operative, and means operatively connecting the movable member and last-named means for movement simultaneously from their stated positions.

4. In combination, an upright revoluble driven structure, clutch members thereon one of which is a driver therefor revoluble on said structure and the other of which is fixed to rotate with said structure and one of said members being shiftable vertically on said structure into and out of clutching engagement with the other member, a support in which said structure is journaled, and means connecting the shiftable member and support and including pivoted toggle members pivoted together and movablein each direction past the dead-center relation to each other and having means to limit their movement in one direction relatively close to their dead-center position.

5. In combination, a revoluble driven structure, clutch members thereon one of which is a driver therefor revoluble thereon and the other of which is fixed to rotate with said structure and one of said members being movable axially of said structure and normally held in clutching engagement with the other, said structure being adapted to be driven in the same direction as it is driven by but independently of and restructure rotates in said direction relatively latively to the driver, and said members to the driver, and means to lock the movable having rachet clutch-engagement portions member on such oamming thereof clear of 10 arranged to positively interlock said memthe other member.
